Neutron stars are highly dense remnants of massive stars that have collapsed, composed mainly of neutrons and other elementary particles. They are observable due to their strong magnetism, rapid rotation, and emission of radio radiation in a narrow cone. ...
A magnetar is thought to consist of a superdense core of neutrons surrounded by a rigid crust of atoms about a mile deep with a surface made of iron. The magnetar’s field is so strong that it creates huge stresses inside that can sometimes crack open the hard crust, causing a starquark...
can gradually transform the neutron stars into the mixed stars consisting in part of mirror dark matter. In quark starstransitions are suppressed. We study the structure of mixed stars and derive the mass-radius scaling relations between the configurations of purely neutron star and maximally...
The stars consist of superfluid neutrons, superconducting protons, and a highly degenerate, relativistic gas of electrons. We use a relativistic 蟽-蠅 mean field model for the equation of state of the matter and the entrainment. We determine the effect of a relative rotation between the neutrons...
Neutron stars consist of extremely dense nuclear matter. Their maximum size and mass are determined by their equation of state, which in turn depends on the interaction potentials between nucleons. Due to the high density, not only neutrons but also heavier strange baryons may play a role. ...
collapsing process takes place. They also don't understand the state of the matter inside of these stars, which are so dense that atoms likely cannot exist in their regular form inside them and instead get squashed into a soup of free-floating quarks (the constituents of protons and neutrons...
Despite the notion, cool neutron stars accommodate, in the crust, various nuclei immersed in a degenerate electron-muon environment (maybe as “pasta” or “spaghetti” or crystalline medium). In the deeper interior, above the neutron drip density, neutrons and light clusters begin to dominate ...
Neutron stars consist of the densest known material in the universe. 据知,中子星是由宇宙中密度最高的物质所组成的。 jw2019 Theoretically, quark stars would be radio-quiet, so radio-quiet neutron stars may be quark stars. 理論上,夸克星是電波寧靜的,因此電波寧靜中子星可能就是夸克星。 Wi...
For example, for pure neutrons the deviation is below 0.9% and for a strongly bound nucleus such as iron the deviation of the average mass from mu would only be ≈ 0.2%. Therefore, we use in the following m0 ≈ mu. We further use from now on the convention that all energies are ...
It should be stressed that the estimated tempera- ture within this simple approximation only accounts for contributions of the ideal gas of neutrons and protons (mass differences have been neglected). Especially at the low-density regions of the outer crust of the hybrid star (which is composed ...
